来自北京化工大学的研究团队构建了一个可高效生产多种芳香酯的微生物平台。他们提出了一种系统工程策略,具体包括重塑底物通道以增强酶的底物特异性,改变乙酰辅酶A的代谢途径以改善辅因子供应,设计动态调控系统以重新分配细胞生长和产物合成之间的碳通量。这些方法使 ...
教科书出版商麦格劳-希尔公司(McGraw Hill)常常要在两种不同观点之间找到平衡。该公司首席数据科学和人工智能官迪伦·阿雷纳(Dylan Arena)认为,这个历史可以追溯到计算器被发明出来的时候。
从宏观磁矩举例,如图6所示。在磁矩足够远的地方测量感生磁场,总磁场强度随距离成呈现三次方反比依赖关系,方向依赖性像一个两端高度与腰部直径之比约为2的花生形状。将磁场正交分解为沿磁矩的纵向分量和与磁矩垂直的横向分量,横向分量的正负转变角度在水平或竖直方 ...
